When I first started I was just putting myself out there as I could design anything for anyone. Then I started getting clients who were looking for design on the cheap and it didn't really matter who they hired.
After I had a few clients under my belt I really understood who I worked best with and the type of services I wanted to offer. I started off offering the world, but it's really effing hard to offer the world as a one-woman show. You can't offer every design service under the sun and be profitable with the amount of money you need to invest in.
